Choroidal　neovascularization　(CNV)　has　been　associated　with　a　wide　variety　of　chorioretinal　disorders,　which　can　cause　vascular　leakage,　bleeding,　and　scar　formation,　leading　to　significant　vision　loss.　The　effective　and　precise　detection　of　CNV　is　essential　for　optimal　disease　management.　A　classification　system　has　been　devised　to　categorize　neovascularization　according　to　its　anatomical　location.　The　system　distinguishes　three　distinct　types　of　neovascularization:　type　1,　type　2,　and　type　3.　According　to　the　exudative　features　of　the　new　vessels,　CNV　can　be　divided　into　exudative　and　non-exudative　categories.　Each　type　of　CNV　exhibits　unique　features　across　various　imaging　modalities.　The　present　study　reviews　contemporary　imaging　modalities　employed　in　the　detection　of　CNV,　with　a　focus　on　the　underlying　mechanisms,　their　respective　advantages　and　disadvantages,　their　typical　clinical　utilization,　and　the　characteristic　features　of　CNV　that　are　discernible　through　these　techniques.　The　exploration　of　novel　promising　imaging　techniques　for　CNV　detection　including　photoacoustic　microscopy,　AI,　photothermal　OCT,　and　functional　fluorescent　angiography　is　also　performed.
